This indicates that the mean of the sample (16.5 seconds) is statistically significantly lower than the mean of the population (18 seconds). Therefore, the researcher can conclude that the noise does cause the mice to complete the maze faster.

Using a two-tailed t-test with a significance level of 0.05, the researcher can conclude that the noise does cause the mice to complete the maze faster. The test statistic for this experiment is -2.097, which is less than the critical value of -1.68. This indicates that the mean of the sample (16.5 seconds) is statistically significantly lower than the mean of the population (18 seconds). Therefore, the researcher can conclude that the noise does cause the mice to complete the maze faster.

There will be 8980 illiterate people in Sylvania 4 years from now if the country continues to reduce the number of illiterate citizens by 5 each year.

We can write a function P(t) to represent the number of illiterate people in Sylvania t years from today, where t is the number of years after the current year.

Given that the country has decided to reduce the number of illiterate citizens by 5 each year, we can subtract 5 from the number of illiterate people each year.

The initial number of illiterate people in the country is 9000. So, the function can be written as:

P(t) = 9000 - 5t

where t is the number of years after the current year.

For example, if we want to find out how many illiterate people will be in Sylvania in 4 years from now, we can substitute t with 4:

P(4) = 9000 - 5(4) = 9000 - 20 = 8980

Therefore, there will be 8980 illiterate people in Sylvania 4 years from now if the country continues to reduce the number of illiterate citizens by 5 each year.

The value of x is 10 and the trapezoid has two base angles with measure 40 degrees and two non-base angles with measure 140 degrees.

What is the congruent angle?

When two parallel lines are cut by a transversal, the angles that are on the same side of the transversal and in matching corners will be congruent.

In an isosceles trapezoid, the base angles (the angles opposite the parallel sides) are congruent. Let's call each of these angles "a". Then, we have:

a = 3x + 10 (from one of the congruent angles)

a = 5x - 10 (from the other congruent angle)

Setting these two expressions equal to each other, we get:

3x + 10 = 5x - 10

Solving for x, we get:

2x = 20

x = 10

Now that we know the value of x, we can substitute it back into either of the expressions for "a" to find the measure of each base angle:

a = 3x + 10 = 3(10) + 10 = 40

Therefore, each base angle of the trapezoid has measure 40 degrees.

The other two angles of the trapezoid are the non-base angles (the angles adjacent to the parallel sides).

These angles are supplementary to the base angles, so each non-base angle has measure:

180 - 40 = 140

Therefore, the value of x is 10 and the trapezoid has two base angles with measure 40 degrees and two non-base angles with measure 140 degrees.

The expression that represents the perimeter of the rectangle in centimeters is 45.2g - 30.6h.

Let's start by finding the length of the top and bottom sides, which are equal to the width. The width is given by (9.8g - 4.5h) centimeters, so the length of the top and bottom sides is:

2(width) = 2(9.8g - 4.5h) = 19.6g - 9h

Next, we need to find the length of the left and right sides, which are equal to the length. The length is given by (1.5g - 3.4h) centimeters, so the length of the left and right sides is:

2(length) = 2(1.5g - 3.4h) = 3g - 6.8h

Now that we have the lengths of all four sides, we can find the perimeter of the rectangle by adding them together:

Perimeter = length + width + length + width

Perimeter = (3g - 6.8h) + (19.6g - 9h) + (3g - 6.8h) + (19.6g - 9h)

Find the probability that the mean amount of work per week for three randomly selected professors is more than 60 hours.Part a) Calculate the value of the test statistic, set up the rejection region, undertake the hypothesis test, and interpret the result.

i) P(X < 96)First, we calculate the z-score as follows:z = (X - μ) / σ = (96 - 100) / 2 = -2P(X < 96) = P(Z < -2) = 0.0228ii) P(96 < X < 105)We first calculate the z-scores for both X values as follows:z1 = (X1 - μ) / σ = (96 - 100) / 2 = -2z2 = (X2 - μ) / σ = (105 - 100) / 2 = 2.5Next, we look up the area between these two z-scores using a standard normal distribution table.

One zero of the polynomial is given. Use it to express the polynomial as a product of linear factors over the complex numbers.

Given: f(x) = x^2 + 3x + 3 and zero: 3

Here's how to approach this problem:

The polynomial f(x) has a root of 3.

f(x) can be expressed as a product of two factors, where the first factor contains (x-3) as one of its roots, as follows:

f(x) = (x-3)(ax + b)

We can obtain the values of a and b by equating the coefficients of this equation to that of the given polynomial:

a + 3 = 1 (since coefficient of x in the given polynomial is 3)

-3a + b = 3 (since the constant term in the given polynomial is 3)

Solving these equations gives us a=-2 and b=9.

f(x) can thus be expressed as:

f(x) = (x-3)(-2x + 9)

Hence, the expression for the polynomial is f(x) = -(x-3)(2x-9).

Triangle XYZ is shifted 9 units to the right, then 4 units down.

The volume of the rectangular prism can be calculated by using the formula V = lwh, where l is the length, w is the width, and h is the height.

The volume of a rectangular prism can be calculated by the formula V = lwh, where l is the length, w is the width, and h is the height. To calculate the volume of a rectangular prism, first measure the length, width, and height of the prism. Then, plug these measurements into the formula V = lwh and solve for V.

For example, if the length of the prism is 6 cm, the width is 5 cm, and the height is 4 cm, the volume can be calculated by plugging these values into the formula. V = 6 x 5 x 4 = 120 cm3. This means that the volume of this rectangular prism is 120 cm3.

Length is a measure of distance or extent, typically referring to the measurement of an object or distance in one dimension. It describes how long an object or distance is, usually in units such as meters, feet, or inches. Length is one of the fundamental physical quantities, and is used in various fields including mathematics, physics, engineering, and construction. It is often represented by the symbol "L" or lowercase "l".

To find the area of the backyard, we need to multiply the length and width of the rectangular shape.

Length of the backyard = 3x - 8

If all three of them together have a total of 520 kroner then bill would have 205 kroner

amounts of money that Alan, Bill, and Cassie have:

Let A be the amount of money that Alan has.

Let B be the amount of money that Bill has.

Let C be the amount of money that Cassie has.

From the problem, we know that:

A + B = 250 (equation 1)

B + C = 475 (equation 2)

A + B + C = 520 (equation 3)

We want to solve for B, the amount of money that Bill has.

One way to do this is to use equation 1 to solve for A in terms of B:

A = 250 - B

We can then substitute this expression for A into equations 2 and 3:

(250 - B) + B + C = 520

Simplifying this equation, we get:

C = 270

Substituting this value of C into equation 2, we get:

B + 270 = 475
